External form filter with jquery datatables

Question

I am trying to make an external filter from an external form

Until then, for a simple generic search, jquery datatables use the parameter 'sSearch'

For that, I just do

  var grid = new $.fn.dataTable.Api('.e-grid');
  grid.search('Teste');
  grid.draw();

All right, but I need to make a slightly more complex filter, which the filter form data is not in the column. I say this, because every filter a little more complex that I found of example, was only of the columns that already existed in datatable

The question is, how do I pass other parameters to that filter? other than the default which is sSearch

OBS: The filter is via Ajax, and how Server Side I am using Asp.net MVC

Follow an example below:

var oTable = $("#dataTableCustom").dataTable({
        "iDisplayLength": 25,
        "bDestroy": true,
        "bProcessing": true,
        "bJQueryUI": true,
        "bAutoWidth": false,
        "bServerSide": true,
        "sAjaxSource": globalSource,
        "sPaginationType": "full_numbers",
        "fnServerData": function (sSource, aoData, fnCallback) {
            $.getJSON(sSource, aoData, function (json) {
                var parsedJSON = $.parseJSON(json);
                fnCallback(parsedJSON)
            });
        },
        "fnServerParams": function (aoData) {
            aoData.push({
                "name": "listName",
                "value": wcfListName
            })
            aoData.push({
                "name": "columnNames",
                "value": wcfColumnsToDisplay
            })
            aoData.push({
                "name": "SortingDirection",
                "value": wcfSortDirection
            })
            aoData.push({
                "name": "sortingColumns",
                "value": wcfSortColumns
            })

        }
    });

The value of "value" can also be an imput, ex:

"value": $(".meuiinput").val();
